John Lewis Harris was born in Birmingham, Warwickshire, England in 1887, the son of Robert and Elizabeth Sarah Ann Harris. When he was not at sea he lived with his brother, Thomas H Harris, at 280 Belgrave Road, Birmingham.
He trained as a butcher and first worked at Moseley, Birmingham and the Central Meat Market, Bradford Street, Birmingham, before joining the crew of the
Lusitania as an assistant butcher in the Stewards' Department in January 1914.
He was serving in this capacity when the liner was torpedoed and he was killed as a result. He was aged 28 years.
His body was never found and identified afterwards, so he is commemorated on the Mercantile Marine Memorial at Tower Hill, London.
